Question

Select the word that can be joined with the given noun to form a compound noun-
Master
(a)Key
(b)Lock
(c)Step
(d)Door

Answer 1

Hint: The given word is ‘master', which can be used in any sentence or phrase with different contexts, which will create different meanings. Only the correct compound word will make sense.

Complete answer: In the given question, we have to join the given word ‘master' with the given noun to form a compound noun, from the four given options. Compound nouns are a combination of two nouns in which the first noun is what kind of a person or object it is or what the purpose of the noun is whereas the second noun identifies the first noun. The word ‘master' is - a skilled practitioner of a particular art or activity. For example: “I’m a master of disguise”
Now, let us examine all the given options to find out the correct option :
Option ‘a’ is Key. It is the correct option as ‘master key’ is an original word. A master key is a key that opens several locks, each of which also has its own key. For example: “the master key for all the safes in the department”
Option ‘b’ is Lock. There is no compound word like ‘master lock'.
Option ‘c’ is Step. There is no such compound word as ‘master step', so it cannot be the correct answer.
Option ‘d’ is Door. There is no such word as ‘master door'. So, we will eliminate this option.
As we have analysed all the other options, we can easily figure out the correct answer. The compound word would be – master key. Hence, the option ‘a’ is the correct option.

Note: Such type of questions may have one or more than one answers as well. You may also have different compound words using one base word. For example, We can use 'master' to create more words, such as 'master card'.
